The number of units of a product sold in three different years and the respective net profits are presented in the figure above. The cost/unit in Year 3 was Re. 1, which was half the cost/unit in Year 2. The cost/unit in Year 3 was one-third of the cost/unit in Year 1. Taxes were paid on the selling price at 10%, 13%, and 15% respectively for the three years. Net profit is calculated as the difference between the selling price and teh sum of cost and taxes paid in that year.

The ratio of the selling price in Year 2 to the selling price in Year 3 is _________.

\begin{array}{|c|c|c|c|} \hline \textbf{Items} & \textbf{Cost} & \textbf{Profit \%} & \textbf{Marked Price} \\ & (Rs.) & & (Rs.) \\ \hline P &5,400 &---&5,860\\ \hline Q&---&25&10,000\\ \hline \end{array}

Details of prices of two items P and Q are presented in the above table. The ratio of cost of item P to cost of item Q is 3:4. Discount is calculated as the difference between the marked price and the selling price. The profit percentage is calculated as the ratio of the difference between selling price and cost, to the cost

(\text{Profit} \%=\dfrac{\text{Selling price - Cost}}{\text{Cost}} \times 100)

The discount on item Q, as a percentage of its marked price, is _______
